The SGI Altix 4700 and the SGI PRISM were decommissioned. The HPC cluster is the now the
primary compuational resource for the University.

September 2015

A new HPC cluster has been installed in the Chemistry Department. This HPC resource consists
of a 320 core cluster with a 32 core login node. The cluster consists of 16 nodes, each nodes
has 20 Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz processors, 128 GB of memory and 1 TB of disk
space. Also, the cluster has 180 TB of shared disk space. This computer has the same application
software is available that was on the Altix 4700.

June 1, 2014

After the recent hardware problems on the Altix 4700 were fixed, the operating system and
intel compilers were updated. Thus we have recompiled and reinstalled the application
software on the Altix 4700. Hopefully, this will remove problems with unresolved references
to libraries that no longer exist.

The hybrid MPI/OpenMP version of MrBayes v3.2.1 by Alexis Stamatakis and Wayne
Pfeiffer has been installed on the SGI Altix 4700. Information about this
version of MrBayes and how to cite the program can be found at
http://wwwkramer.in.tum.de/exelixis/software.html.
MrBayes is a program
for the Bayesian estimation
of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior
probability distribution of trees, which is the probability of a tree conditioned on the
observations. The conditioning is accomplished using Bayes's theorem. The posterior
probability distribution of trees is impossible to calculate analytically; instead,
MrBayes uses a simulation technique called Markov chain Monte Carlo (or MCMC) to
approximate the posterior probabilities of trees. A script to run the hybrid Mrbayes
can be found:

There are analytic gradients for both restricted and unrestricted Hartree-Fock
(RHF and UHF, respectively) reference functions. In addition, for the MBPT(2),
MBPT(3), CCSD, and CCSD(T) methods, analytic gradients are available for
restricted open-shell Hartree-Fock (ROHF) reference functions. They are
also available for certain CCSD calculations based on quasi-restricted
Hartree-Fock (QRHF) reference functions, namely those for high-spin doublet
cases and two-determinant CCSD (TD-CCSD) calculations for open-shell singlet
states, in which the open-shell orbitals have different symmetries.

GULP is a program for performing a variety of types of simulation on materials using
boundary conditions of 0-D (molecules and clusters), 1-D (polymers), 2-D (surfaces,
slabs and grain boundaries), or 3-D (periodic solids). The focus of the code is on
analytical solutions, through the use of lattice dynamics, where possible, rather
than on molecular dynamics. A variety of force fields can be used within GULP spanning
the shell model for ionic materials, molecular mechanics for organic systems, the
embedded atom model for metals and the reactive REBO potential for hydrocarbons. Analytic
derivatives are included up to at least second order for most force fields, and to
third order for many.

If you want a graphical interface to GULP, look here:

http://gdis.sourceforge.net

Accelry's Materials Studio may also be used to setup GULP input files. These can then be transferred
the Altix and submitted to LSF to run.
